[c-nsp] A couple of PIX questions

[Scott Klassen]

Using 506e with latest Pix OS and PDM.  Two questions.  

Under Config>VPN>IKE>Policies, for Identity, it is now set to hostname.
What if any would be the possible issues with setting this to IP Address?

Recently our PIX started exhibiting a strange behavior.  It doesn't seem to
be releasing VPN IP Addresses back to the configured pool after the client
disconnects.  Anyone have some pointers of things I can look at for this?

Thanks,

Scott Klassen
